Changed pinion seal and crush sleeve. Makes everything go smoothly and ensure proper alignment. Not something I would skimp on. Top quality.

It worked but the metal is soft both the yoke attachment (tool) and the holding bar. It will work for a “one timeâ€. The bar bent and the metal actually separated (split) while using the bar over the boss. I used the 3/4 adapter hole to finish the job. (Which began to deform as well). I do not recommend this product for professional use (no I’m not a professional but I do this several times a year). I gave it two stars because it finish the job. It would be a great tool if stronger metal was used. Personally I will not be using this tool again. Just the truth.
